MUD GUARD FOR MOTOR VEHICLES.

Be it known that I, JOSEPH JOHN WAM- rAcH, a citizen of the United States of America, residing at Berlin-Charlottenburg, Germany, have invented certain new and useful Improvements in Mud Guards -for Motor Vehicles, of which the following is a specifivMy invention relates to mud guards for motor vehicles and more especially to at- Y tachrnents adapted to be applied to the mud guards hitherto used. It is an object of my invention to supplement the usual mud guards by saidattachments so as to prevent soiling of those 'parts of the vehicle which are not protected by these guards.

In the drawings affixed to this specication and forming part thereof a device embodying my invention is illustrated diagrammatically by way of example.

In the drawings:

Fig. 1 is an elevation of the lower parts of a motor car, the mud guards of which are equipped with mv novel attachment,

. Fig-2 isasimilar illustration of the mud guards with the principal parts of the attachment removed,

' Fig. 3 is .a horizontal section on the line rig. 1.

111411 in Fig. 1,

- Fig. 4 is a vertical section the line Fig. 4a shows a detail on a-larger scale,

`Fig. 5 is a front elevation illustratingwonv a larger scale the means for securing the at- -tachnient to a wing of the mud guards, and

Fig. 6 is a sectionpon the line VI-VI in l `he wings of the mud flanges 1 on the outside. Preferably the edges of the anges are beaded at 2 and strengthened by insertion wire 3 (as shown guard have vertical 4 in Fig. 6). Longitudinal slots 4 with extensions 5 at right anglesl to the slots are formed .the handlingof the bolts;

T e attachment 1s adapted to be secured to thc wings by means of theseslots as will be described further below. The attachment for the mud guards of the non-steered wheels, as a rule the rear wheels, is a semi- .circular oisubstantially semi-circular plate 6 which is recessed to leave room for the axle. The plate is secured in the slots 4, 5 by means of bolts 7, the heads of which are bent to annular shape in order to facilitate A nut 9` is placed o'n the threaded Ainner end of each bolt and a coiled spring 11 is inserted betweenthe nut and a washer 10 on the inner surface of the beaded and equipped with insertion wire like the flange l, is placed against the flange 1 and secured thereon by a plurality of bolts 7. The bolts are held in holes of the plate 6 and their annular heads 8 are 'so adjusted as to enable them to pass through the slots 4. When the plate 6 is in position on the iiange 1, the bolts are turned 90 vso that their heads partly enter the transverse extensions 5 of the slots 4 under the action of the springs 11, and are secured therein in such a manner as to be readily detachable.

The mud guards of the front orsteering wheels are equipped with a crescent shaped attachment 12 which is secured to the ange 1 ofthe wing by meansof bolts 7 as described with reference to the plate 6. The inner diameter ofthe crescent 12 is somewhat larger than that of the wheels so that a wheel can freely move in the corresponding crescent. A bracket 13 is secured at-'the top of the crescent 12 and a vertical bolt 14 isv held in the bracket. Segment-shaped .aps 15 and 16 hingedfto this bolt are recessed at thelr inner ends for the axle journal.

yond the inner edge lof the crescent 12 and the aps 15, 16 are-held to the crescent by a spring 17 on the bolt`14. 4A roller 18 is secured on the inside of each flap 15 and 16 in the vicinity of their horizontal lower edges and extending in parallel thereto. The rollers 18 are carried in ball bearings 19 as shown in Fig. 4a.

The plate 6 and the flaps 15, 16 guard the wheels to the extent requlred for protecting the car body and the passengers from splashes.

The swivelling motion `of the steering wheels is accounted for by the hinged and resilient arrangement of the flaps 15, 16 which are free to turn on their hinge bolt 14 against the action of the spring 17 when the.

wheel engages one of the rollers 18, .as indicated in full lines on the left hand side, and

in dot-and-da'sh lines on the right hand side The rollers 18 act as antifrictfion bearings The' v outer edge of each iap projects slightly belua between the wheels and the flaps' so that wear and damage to the wheels, the tires and the fiaps are prevented. u

The fiaps, the crescent 12 and the plate 6 may be made of any suitable material, such as sheet metal, Celluloid or the like.

It will be understood from the foregoing description that the attachment is readily detachable Wit-hout the aid of tools when not required, for instance on a dry road or in case of repairs, and is as readly placed in position., I Wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

I claim:

Mud guard for motor vehicles comprising. a verticalv flange on the guard, a crescent shaped attachment adapted to be secured to said flange, headed bolts extending throu l1 elongated registering slots in said attac 1- ment and said flange, coiled springs encircling said bolts so as to hold said attachment applied against said flange, a hinge bolt mounted on said attachment, spring-controlled flaps hinged to said bolt and a roller on the inside of each flap and adapted to be engagedV by said Wheel. v

In testimony whereof I affix my signature.

JOSEPH JOHN WAMPACH.
